Currently the extension of human activities allows us to characterize the human being as a geological and biological forcing, capable of generating significant alterations both in the geochemical composition of the main reservoirs of the Earth surface and in biodiversity. Substantial variations of the atmosphere composition as well as of sedimentary constituents deposited in lacustrine environments and in coastal zones allow to easily identifying the anthropic influence on Terrestrial ecosystems. However, the nature of a forcing does not characterize the beginning of a new geological interval, but the extension of its expression on the Earth system. These issues raise a vigorous debate that seeks to understand not only how the human affects the planet, but also how much we can change surface geochemistry and biological activity. In this context, the search for a marker of Anthropogenic effects in geological materials is an important criterion for determining the Anthropocene as a new geological event on the planet. This paper proposes a brief discussion of the scale about environmental changes due to the anthropic action on the planet surface and its signature in the biogeochemical reservoirs with a view to presenting a suggestion for the beginning of the Anthropocene. Finally, we ponder the fact that we are not the first biological forcing to change the surface of the planet, but without doubt, we are the first forcing that has a moral dimension. (AU) | |
